Lumencor's light engines are unique, solid state illuminators, ideally suited for use
with fluorescence microscopes and bioanalytical instruments.

The SPECTRA is optimized for the most common fluors and fluorescent proteins used in bioanalysis today.
Bright outputs cover the visible spectrum and beyond, with particularly impressive performance in
the typically underserved visible spectral regions - green, yellow and red.

Micro-second switching among color bands (5-10 kHz)

No mechanical shuttering or filter movement

Easy to install - pre-aligned

Couples to microscope with liquid light guide

Customer may select bandpass filters when ordering

Lifetime expected to be 20,000 hours, 36 month warranty

Lumencor SPECTRA X Light Engine

Lumencor now offers the spectral breadth of an arc lamp and the flexibility of a filter
wheel in it's most powerful and comprehensive light engine design.

The SPECTRA X model has been released to afford the end user the ability to
exchange single band pass filters within the light engine. These field replaceable
filters mean Lumencor can offer as many as 21 different bandpasses for use within
the visible spectrum.

User-replaceable bandpass filters

Includes a suite of 7 bandpass filters; additional paddles and filters can be added

The DG-4/DG-5 Plus are a combined Xenon Arc lamp and high speed wavelength switchers, ideal for
fast ion imaging where image ratios at different excitation wavelengths are required at
high frame rates.

The unique optical design of the Lambda DG-4/DG-5 Plus is based on dual scanning galvanometers
utilizing interference filters for wavelength selection. The filters are user-replaceable without
affecting alignment.

Sutter Instrument introduces two new filter changers specially designed for wavelength
selection over a wide spectral range to any given nanometer value. The Lambda VF-5 and
Lambda VF-1 employ the innovative VersaChrome® thin-film filter technology from Semrock
to provide outstanding bandpass characteristics such as high transmission (close to 100%),
steep edges and out of band blocking. Since these filters pass an image, they are equally
suitable for emission and excitation paths.

A specific wavelength within the wide spectral range of each filter is obtained by adjusting
the angle of incidence from 0 to 60 degrees. This tuning causes little or no change in spectral
performance of the filter regardless of the state of polarization of the light passing through the filter.
The current VersaChrome® series has 7 filters covering 338 to 800nm. By simply selecting the desired
center-wavelength on the controller, the Lambda VF-5 automatically moves and tilts one of its
five filters into position. Users can select any combination of filters offered by Semrock
for the Lambda VF-5 (which holds up to 5 filters) or any single filter in the series for the Lambda VF-1.

Wavelength range as wide as 338-800nm

Access any center-wavelength in nanometer increments

Images pass through filters making it suitable for both excitation and emission

Easily switch between fluorphore combinations

Optional liquid light guide offers absolute vibration isolation

All the advantages of thin-film technology - high transmission, steep spectral edges, high out-of-band blocking
